An information board in the aquarium will provide information about this fish.

"Neon tetras get their names from the beautiful blue metallic line on their bodies. Although their shy, gentle fish, surprisingly they're related to piranha, though very distantly. They have very sharp and narrow teeth, an odd contrast to their beauty. They are delicate fish who tend to be very sensitive to the cleanliness and temperature of water."

The Neon Tetra is a freshwater fish. It is native to blackwater or clearwater streams in southeastern Colombia, eastern Peru, and western Brazil, including the tributaries of the Solimões where the water is between 20–26 °C (68–79 °F).

The neon tetra has a light-blue back over a silver-white abdomen. The fish is characterized by an iridescent blue horizontal stripe along each side of the fish from its nose to the base of the adipose fin, and an iridescent red stripe that begins at the middle of the body and extends posteriorly to the base of the caudal fin. Most, if not all, will develop an olive green sheen lining their backs. The fish is completely transparent (including fins) except for these markings. During the night, the blue and red become silver as the fish rests—it reactivates once it becomes active in the morning. It grows to approximately 3 cm (1.2 in) in overall length.
